A sand bar has built up at the end of the Pohoiki boat ramp, but the ramp itself remains intact and there has been no significant lava advance toward the ramp in recent days.

Fissure 8 may have slowed down, but HVO scientists are still on the ground in Leilani Estates, monitoring old ground cracks and marking ones that haven't been surveyed before. Monitoring these cracks over multiple days could detect any new signs of magma movement beneath the ground, one of the indicators that fissures might reactivate.

Today's morning overflight saw no new activity at any of the fissures in the lower East Rift Zone. Fissure 8 had only a sluggish lava puddle remaining in the cone, and other fissures, though steaming, showed no signs of reactivation.

This thermal map shows the fissure system and lava flows as of 6 am on Saturday, August 11. Residual lava in the Fissure 8 flow continues to drain, feeding numerous small ocean entries (shown in main map). In the Fissure 8 cone there were two small lava ponds (shown in small inset map). The black and white area is the extent of the thermal map.

The UAS team (Unmanned Aircraft Systems) flew a mission over fissure 8 to assess conditions within the cinder cone. As shown, fissure 8 contains two small ponds deep within its crater. One pond slowly circulates with an incandescent surface while the other pond is stagnant with a crusted top.

Clear weather this afternoon afforded a stunning view of Kīlauea's summit, which has been "quiet" since August 4, with no significant subsidence or collapses. The flat ledge shown here (center) is part of the former Halema‘uma‘u crater floor, which dropped precipitously between mid-May and early August.

The flat ledge shown here (center) is part of the former Halema‘uma‘u crater floor, which dropped precipitously between mid-May and early August.
As the Halema‘uma‘u Crater has collapsed, geologists have been able to see older volcanic deposits and features buried beneath decades of lava flows. For instance, two lava tubes were spotted in the southwestern wall of the collapse crater.

Map as of 2:00 p.m. HST, August 9, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

Northern Fulmars, Black-legged Kittiwakes, and Common Murres have all been tested for and contained harmful algal bloom (HAB) toxins. Since 2015, the USGS has worked with a variety of stakeholders to develop testing methods and research projects to better understand the geographic extent, timing and impacts of algal toxins in Alaska marine ecosystems.

Hydrologic technician Kammy Durham reading the elevation of a known reference point at streamgage 06404998, Grace Coolidge Creek near Game Lodge near Custer, SD. One step in ensuring consistent streamflow data is verifying that the reference elevation at the streamgage stays consistent and that any changes are documented.
